RY5522 = SKY85717 & RTC5638H

5.15–5.85GHz 802.11ac Front End Module

The RY5522 is a complete integrated 5GHz Front-End Module (FEM) for an IEEE 802.11ac system. It includes a
highly linear 5GHz Power Amplifier (PA) with power detector, Low Noise Amplifier (LNA) with bypass capability,
and SPDT antenna switch. This highly integrated FEM only requires one bypass cap thus reducing system footprint,
bill of materials, and manufacturing cost.
The LNA and PA disable functions ensure low leakage current inoff mode. An integrated power detector is included
to provide closed-loop power control within the system.
The RY5522 is available in a 16-pin low profile 3×3×0.65mm QFN Package
